Rainbow Molecular Weight Markers have been enhanced to enable faster and simpler identification of proteins on SDS-polyacrylamide gels. The ready-to-load markers provide sharper, more intense bands on gels and blots and have improved band spacing for more accurate molecular weight determination. The bright, distinctive colors of the markers allow easier confirmation of transfer to blotting membranes and orientation.

High-Range Rainbow Molecular Weight Markers are comprised of eight separate proteins with six different visible colors, not visible on a chemiluminscence image. Each 250 µl pack size is sufficient for use with 50 minigels (10 x 8 cm) or 25 large gels (20 x 20 cm).
